Abstract
Description
Technical Field
[0001] This utility model belongs to the field of polystyrene car parts model processing technology, specifically relating to a dual-station polystyrene car parts model material gripping mechanism. Background Technology
[0002] Polystyrene, scientifically known as expanded polystyrene (EPS), is a polymer foam material formed by high-temperature foaming of polystyrene with a foaming agent. Its interior is filled with numerous interconnected micropores, giving it properties such as light weight, heat insulation, sound insulation, shock absorption, and excellent cushioning. It is widely used in the manufacture of automotive parts models, often for making car seat cushioning pads, dashboard damping modules, and door interior shock-absorbing layers, among other parts models.
[0003] In the production of automotive parts models, polystyrene material is widely used in packaging and model making due to its good cushioning properties and light weight.
[0004] The dual-station polystyrene automotive parts model material gripping mechanism, with "parallel operation" as its core, achieves a dual breakthrough in production efficiency and quality. Through the synchronous operation of two independent gripping units, this mechanism can simultaneously grip and transfer polystyrene materials from different positions, nearly doubling the efficiency compared to single-station equipment and significantly shortening the production cycle of automotive parts models.
[0005] Existing dual-station clamping mechanisms use mechanical grippers to clamp and move materials that need to be processed. However, polystyrene foam is lightweight, fragile, and has a porous surface. When clamped, it is easy for the material to deform and break due to the pressure, which in turn leads to a decrease in the yield rate. Utility Model Content
[0006] The purpose of this utility model is to provide a dual-station polystyrene automotive parts model material gripping mechanism, which aims to solve the problem that existing dual-station clamping mechanisms use mechanical grippers to clamp and move materials to be processed. However, polystyrene foam is lightweight, fragile, and has a porous surface, which can easily lead to material deformation and damage due to clamping pressure, resulting in a decrease in yield.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a dual-station polystyrene automotive parts model material gripping mechanism, comprising a gantry-type dual-station, a longitudinal column slidably connected to the surface of the gantry-type dual-station, a base plate connected to the bottom surface of the longitudinal column, a motor mounted on one side of the base plate, a bidirectional lead screw connected to the surface of the motor shaft, the other side of the bidirectional lead screw sleeved within a bearing provided on the surface of the base plate, a threaded block slidably connected to the surface of the base plate, the threaded block threadedly connected to the surface of the bidirectional lead screw, the threaded block threadedly connected to a clamping block by a fixing bolt, an installation groove formed on the longitudinal end surface of the clamping block, a pressure sensor fitted into the surface of the installation groove, the pressure sensor abutting against a clamping ring, a spring connected to the other side of the clamping ring, the other side of the spring connected to the inner wall of the clamping block, an adjusting rod connected to the surface of the clamping block, a rubber block bonded to the surface of the adjusting rod, the rubber block engaging with the intersection of the clamping block and the installation groove, and the adjusting rod movably connected to the surface of the installation groove.

[0010] As a preferred embodiment of the dual-station polystyrene automotive parts model material gripping mechanism of this utility model, the clamping ring is a semi-circular structure, and the shape and size of its inner wall arc structure are adapted to the pressure sensor.

At the same time, the clamping ring and adjusting rod are used to fix the position of the pressure sensor on the clamping block, which facilitates the periodic removal and replacement of the installed pressure sensor.

[0023] Please see Figures 1-4This utility model provides the following technical solution: A dual-station polystyrene car parts model material gripping mechanism, including a gantry-type dual-station 1, a longitudinal column 2 slidably connected to the surface of the gantry-type dual-station 1, a base plate 3 connected to the bottom surface of the longitudinal column 2, a motor 4 mounted on one side surface of the base plate 3, a bidirectional lead screw 5 connected to the shaft surface of the motor 4, and the other side surface of the bidirectional lead screw 5 sleeved in a bearing provided on the surface of the base plate 3, a threaded block 6 slidably connected to the surface of the base plate 3, the threaded block 6 threadedly connected to the surface of the bidirectional lead screw 5, and the threaded block 6 threadedly connected to a clamping block 8 by a fixing bolt 7, a mounting groove 9 opened on the longitudinal end surface of the clamping block 8, and a pressure sensor 10 fitted into the mounting groove 9. 10 Surface abuts against clamping ring 11, the other side surface of clamping ring 11 is connected to spring 12, the other side surface of spring 12 is connected to the inner wall of clamping block 8, the surface of clamping block 8 is connected to adjusting rod 13, the surface of adjusting rod 13 is bonded to rubber block 14, the surface of rubber block 14 is snapped to the intersection of clamping block 8 and mounting groove 9, and adjusting rod 13 is movably connected to the surface of mounting groove 9. In this design, gantry double station 1, longitudinal column 2 and base plate 3 constitute the main body of gantry double station clamping device, and a large number of related components are set in the main body of gantry double station clamping device. Since they are existing technologies and the core content of this technical solution is not related to them, they will not be described in detail in this technical solution.
[0024] In use: This gantry-type dual-station polystyrene automotive parts model material gripping mechanism, based on a Cartesian coordinate system, achieves precise positioning through the coordinated motion of the x, y, and z axes. The control system issues commands to drive the motor, which, via the transmission device and guide rails, moves the base plate 3 of the dual-station design in three-dimensional space. Upon reaching the target position, the clamping blocks 8 mounted on the surface of the base plate 3 grip the polystyrene material at the bottom and then transfer it to the designated location according to instructions, completing the material handling process. The two stations can operate in parallel or alternately, improving gripping efficiency.
[0025] Preferably, two sets of threaded blocks 6 are threadedly connected to the surface of the bidirectional lead screw 5.
[0026] In practical use, two sets of threaded blocks 6 are respectively threaded to both sides of the surface of the bidirectional lead screw 5, so that the rotation of the bidirectional lead screw 5 can simultaneously adjust the movement of both.
[0027] Preferably, the clamping block 8 is an L-shaped integrated structure, and a rectangular groove is opened on the top surface of the clamping block 8, and the shape and size of the groove are adapted to the bottom of the threaded block 6.
[0028] In practical use, the groove on the top of the clamping block 8 is used to fit its top onto the bottom of the threaded block 6, and the connection between the two is fixed by the fixing bolt 7, so that it can be easily replaced and connected to the threaded block 6.
[0029] Preferably, the clamping ring 11 has a semi-circular structure, and the shape and size of its inner wall arc structure are adapted to the pressure sensor 10.
[0030] In practical use, two clamping rings 11 are respectively abutted against the surface of the pressure sensor 10 to clamp and fix it.
[0031] Preferably, the motor 4 and the pressure sensor 10 form a signal-control closed-loop connection structure.
[0032] In practical use, the control device connected between the motor 4 and the pressure sensor 10 is used to convert the detected physical quantity of pressure into an electrical signal when the clamping block 8 is under pressure, and the control device controls the opening and rotation of the motor 4.
[0033] Preferably, the clamping block 8, the clamping ring 11, the spring 12 and the adjusting rod 13 form an elastic connection structure.
[0034] In practical use, after placing the new pressure sensor 10 in the middle of the mounting groove 9 opened on the surface of the clamping block 8, the adjusting rod 13 is moved to both sides again. Then, the elastically connected spring 12 drives the connected adjusting rod 13 to bounce back to both sides of the surface of the pressure sensor 10, so that the clamping ring 11 abuts and clamps the pressure sensor 10 to the surface.
[0035] Preferably, a semi-circular groove is formed on the inner wall of the clamping block 8, and the shape and size of the groove are adapted to the rubber block 14.
[0036] In practical use, the rubber block 14 on the surface of the adjusting rod 13 is engaged with the groove on the inner wall of the clamping block 8 to fix the position of the adjusting rod 13.
[0037] Working Principle: During the processing of polystyrene automotive parts model materials, a motor 4 mounted on the base plate 3, through a connected control device, adjusts the position of the clamping block 8. The motor 4 starts, driving the bidirectional lead screw 5 to rotate. Simultaneously, two sets of threaded blocks 6, threaded onto the surface of the bidirectional lead screw 5, move the clamping block 8 towards the center, thus clamping the polystyrene automotive parts model material. When the clamping block 8 contacts the polystyrene model material, the pressure sensor 10 converts the detected pressure signal into an electrical signal, which is transmitted to the control system via a shielded cable. The control system amplifies and filters the signal before comparing it with a preset pressure threshold. If the detected pressure is below the lower threshold, the control system sends a command to the motor 4 driver to increase the output current of the motor 4, causing the bidirectional lead screw 5 to rotate faster and further tighten the clamping block 8. If the detected pressure is above the upper threshold, the control system sends a command to decrease the output current of the motor 4, causing the clamping block 8 to loosen. By continuously monitoring and adjusting in real time, the clamping force is kept stable within the set safety range, achieving flexible clamping of the polystyrene model material and avoiding damage. In the scenario of small-batch customized production of automotive parts models, product specifications change frequently, requiring regular calibration or replacement of the pressure sensor 10 to adapt to different polystyrene material properties. The adjusting rod 13, elastically connected to one side of the clamping block 8, can be grasped to disengage the rubber block 14 adhered to its surface from the clamping block 8, thereby pulling the adjusting rod 13 to move to both sides. This causes the clamping ring 11, which abuts against the surface of the pressure sensor 10, to move away from the clamped pressure sensor 10, thus allowing for the disassembly and... After replacing the pressure sensor 10, place it in the mounting groove 9 on the surface of the clamping block 8, and then move the adjusting rod 13 to both sides again. Then, the elastically connected spring 12 drives the connected adjusting rod 13 to rebound to both sides of the surface of the pressure sensor 10, so that the clamping ring 11 abuts against and clamps the surface of the pressure sensor 10. The rubber block 14 on the surface of the adjusting rod 13 is engaged and connected to the groove on the inner wall of the clamping block 8, thereby fixing the position of the adjusting rod 13. This stabilizes the replaced pressure sensor 10, ensuring the sensitivity of the pressure sensor 10, and adjusting the clamping distance between the two clamping blocks 8 and the pressure between the surfaces of the polystyrene automotive parts model material.
